A controversial new study from researchers at the University of Minnesota Twin Cities has found a correlation between left-wing political beliefs and higher intelligence levels, as measured by IQ scores and genetic markers.
The study, published in the journal Intelligence, examined data from over 200 families, including both biological and adopted children. The researchers found that individuals with higher IQ scores and genetic indicators of greater cognitive ability tended to hold more liberal and left-leaning political views.
“We find both IQ and genetic indicators of intelligence, known as polygenic scores, can help predict which of two siblings tends to be more liberal,” explained study author Tobias Edwards. “This implies that intelligence is associated with political beliefs, not solely because of environment or upbringing, but rather that the genetic variation for intelligence may play a part in influencing our political differences.”
The researchers tested for five key political variables: political orientation, authoritarianism, egalitarianism, social liberalism, and fiscal conservatism. They discovered that higher intelligence was correlated with greater social liberalism and lower authoritarianism, even after accounting for socioeconomic factors.
However, Edwards cautioned against drawing overly simplistic conclusions, noting that the relationship between intelligence and political beliefs is likely complex and context-dependent. “There is no law saying that intelligent people must always be supportive of particular beliefs or ideologies,” he said. “The way our intelligence affects our beliefs is likely dependent upon our environment and culture.”
The study’s findings are sure to ignite further debate around the relationship between cognitive ability, genetics, and political ideology. While the research provides intriguing insights, Edwards acknowledged the inherent challenges in studying such a multifaceted and contentious topic.
“Intellectuals have flirted with and been seduced by dangerous ideologies and tyrannical regimes,” he added. “Many smart people have believed ideas that are downright stupid. Because of this George Orwell doubted that the intelligence of partisans could be any guide to the quality of their beliefs.”
As with any study on this subject, the findings are likely to be met with both acclaim and criticism, underscoring the need for continued nuanced and thoughtful exploration of these complex issues.
